Re: [geomesa-users] Anyone have experience with Geomesa and Storm?

Hi Joel, Thanks for the reply! I getting around to looking and was wondering if it was not making it onto the classpath. Good to hear that it works!

Let us know if there's anything we can do to help you transition.

I am Aaron's colleague and wanted to pass along the solution. We simply needed to add the Scala dependency in our Storm pom and it worked like a champ. 

        <dependency>

            <groupId>org.scala-lang</groupId>

            <artifactId>scala-library</artifactId>

            <version>2.10.5</version>

Thanks for offering to help out .. we recently are trying to transition from Geomesa rc-2 to rc-5; we discovered the shading/exclusion problem with kryo (that was fun); we are also upgrading from storm 0.8.2 to 0.9.4 and we are getting this run-time error:

java.lang.IncompatibleClassChangeError: Found class scala.collection.mutable.ArrayOps, but interface was expected

        at org.locationtech.geomesa.core.data.AccumuloDataStoreFactory.createDataStore(AccumuloDataStoreFactory.scala:68)

Here’s line 68:

val configuredAuths = authsParam.lookupOpt[String](params).getOrElse("").split(",").filter(s => !s.isEmpty)

We didn't experience any of this until recently trying to upgrade.  Any thoughts or experience with this sort of error?

Hi Aaron,

We use GeoMesa as a sink for data from Storm processing topologies. At the current moment we are using GeoMesa rc-6, Hadoop 2.2, Accumulo 1.5.1, Storm 0.9.2, and Scala 2.10.4 (possibly 2.10.5 which I can verify).

There's probably some shading/exclusions that we have done along the way for kryo or other libraries.

Are there any specific issues you're running up against? We'll be glad to help if we can.

Andrew

Does anyone have experience with Geomesa and Storm .. any versioning issue between geomesa/storm and/or incompatible versions of scala?
